We visited both Ogijima and Megijima and preferred Ogijima. Both islands have lots of friendly stray cats living there. Ogijima is smaller but we liked the houses built on the slopes and the narrow alleys leading to the different houses (some are in ruins n abandoned I believed). There are also various art work done on the houses and the most prominent is the interesting architecture serving like a tourist info center near the jetty. To see the lighthouse you have to walked about 30mins so unless you have time may not be worth going all the way there..
